Episode 31: Coaxial and Twinaxial Cables

This episode covers coaxial and twinaxial cables, two copper-based media types that still appear in both exam questions and some practical environments. Coaxial cable uses a central conductor surrounded by insulation and shielding, which provides protection against interference and supports technologies like broadband Internet and older Ethernet standards. Twinaxial cable, often used in high-speed data center environments, features two conductors with shielding, making it suitable for short-distance, high-bandwidth applications.You will also explore the advantages and limitations of each medium. Coaxial supports long-distance runs with resistance to noise but has largely been replaced by twisted pair and fiber in modern networks. Twinaxial offers low latency and high throughput for server-to-switch connections but is limited by distance. By recognizing these characteristics, you will be able to distinguish cable types on the exam and understand when they are still relevant in professional networking environments.
